Patent CA-2370768-A1 (CA)
Title: Digital subscriber optical fiber transmission system
Inventor: SHIBUTANI MAKOTO
IPC: H04B10/00
Filed: 2000-04-18
Abstract: A fiber-optic subscriber transmission system is provided for accommodating a  plurality of digital subscriber line signals and telephone signals. A plurality of subscribers is connected through telephone lines with remote nodes, which are connected with a terminal office through optical fibers. Remote nodes convert the signals sent by subscribers through telephone lines  into digital signals. Then, the remote nodes convert the digital signals to light signals by time-division multiplexing and send them to the terminal office through optical fiber cables. The terminal office receives the light signals and extracts the original subscriber signals by demultiplexing and D /A conversion of the received light signals. Telephone signals and xDSL (x digital subscriber line) signals, which are multiplexed in the subscriber signals, are separated by a splitter and terminated by a telephone switch an d an xDSL access multiplexer, respectively.

Patent CA-2418397-A1 (CA)
Title: Gas entrainer
Inventor: ARMSTRONG RICHARD JAMES
IPC: B01F27/93
Filed: 2003-02-07
Abstract: The gas entrainer is a rotodynamic machine for trapping and dispersing bubbles of air into a pool of water. A flat circular disc is mounted for rotation close to and concentric with one end of an open cylindrical tube of equal diameter to form an annular nozzle therebetween. Upon the disc and tube end being immersed in water, the spinning disc draws air down the tube and out through the nozzle to disperse it as fine bubbles into the pool. The faster the disc is spun, the more air bubbles are produced; and this at a considerable depth of water. The disc or rotor employed is without blades or paddles and accomplishes entrainment simply by viscous friction between the disc and water in combination with the closely spaced tube end.

Patent CA-2432685-A1 (CA)
Inventor: SOECHTING FRIEDRICH
IPC: F01D5/18
Filed: 2003-06-18
Abstract: A turbine blade applicable to a gas turbine has a turbine blade body havi ng film cooling holes, the interior space of which is partitioned into two cavities by a rib. Hollow inserts each having impingement holes are respectively arranged in th e cavities to form cooling spaces therebetween. Communication is ensured between the cavities by a communication means, so that the impingement cooling is interrupted with respect to the prescribed side having a good heat transmission in the turbine blade body. A partition wall is further arranged between the rib and the insert arranged in the trailing-edge side, thus providing a separation between the cooling spac es respectively arranged in the rear side and front side. Thus, it is possible to noticeably reduce the amount of cooling air in the turbine blade body; and it is possib le to reduce temperature differences entirely over the turbine blade body as small as possible.
